It's the standard way to do that. If you are using gcc/g++ on Solaris, as far as I know it should work the same as on any other OS. It's conceivable that Solaris linker knows things which would permit inter-language linking without extern "C." Unless you find an expert on inter-Solaris compatibility (given there are several incompatible Solaris architectures), if this is not a crucial subject of your project, you should avoid it. C++ linkage supports over-loaded functions, C linkage doesn't.
